Hey folks! Newbie here. I'm using a

class MyFragmentAdapter: FragmentStateAdapter

subclass to use with a ViewPager2 list of fragments. Inside it I store an array of

MyFragment: Fragment

classes (i.e.

MyFirstFragment: MyFragment

and

MySecondFragment: MyFragment

) that I then instantiate inside

FragmentStateAdapter.createFragment(position: Int)

by invoking something like

myClassesList[position].newInstance()

. It is my understanding that instantiating

MyFragment

subclasses inside this function is better, because it manages memory allocation and deallocation (instantiate and destroy) automatically. But this means that I need to create

MyFragment

subclasses for each different Fragment even if code is the same, only layout differs. My question is: Do object expression such as

object: MyFragment { }

also instantiate the Fragment? As far as I could read, these are only data classes, and do not allocate UI/state resources just from the

Fragment

constructor -

onCreate()

isn't invoked correct? And if I were to store in

myClassesList

the

object: MyFragment(layout_id: R.layout.some_layout_id)

could I still be able to somehow instantiate the Fragment inside

createFragment(position: Int)

? Do I still need to "deallocate" objects or does Kotlin automatically sort that out for me when

MyFragmentAdapter.myClassesList

is destroyed?
